Application filed January 16, 1912. Serial No. 671,435.

To all whom it may concern Be it known that 1, WILLIAM A. Denounn'rr, a citizen of the United States, and resident of New York cit borough of the Bronx, in the county 0 New York and State of New York, have invented certain new and useful Improvements in Means for Carbureting Air, of which the following is a specification.

The object of my invention is to produce inflammable mixture from hydrocarbon oil, such as kerosene, capable of use for illumination, power, and other purposes.

My invention comprises novel details of improvement and combination of parts that will be more fully hereinafter set forth and then ointed out in the claims.

Re erence is to be had to the accompanying drawings formin r part hereof, wherein,

Figure 1 is a part y sectional side elevation of an apparatus embodying my invention; Fig. 2 is an enlarged sectional view on the line 2, 2, in Fig. 1; Fig. 3 is a similar view on the line 3, 3, in Fig. 1; Fig. 4 is an enlarged detail section through t e lower portion of chamber 3; Fig. 5 is a section on the line 5, 5, in Fig. 4; Fig. 6 is a sectional detail of a modification of the lower portion of chamber 16, the section bein taken on the 'line 6,6, in Fig. 7, and Fig.% is a plan view of Fig. 6.

Similar numerals of reference indicate corresponding parts in the several views.

The numeral 1 indicates a tank or vessel adapted to contain a supply of compressed air, which may be supplied thereto by any suitable air compressor, indicated at 2.

At 3 is a chamber or tank of suitable construction adapted to contain hydrocarbon oil or the like, such as kerosene oil, indicated at 4.

At 5 is a suitable filling device connected with chamber 3, the same being shown provided with a closure pressure in chamber 3. The tank 1 is connected, by suitable piping 7, with a pipe 8 leading to the lower portion of chamber 3, pipe 8 being shown depending within such chamber.

At 9 is a check valve to prevent return pressure from chamber 3 through pipe 8,

and at 10 is a cock to shut oilcommunication between tank 1 and chamber 3 when desired.

6 adapted to resist air Pipe 8 communicates at its lower end with a substantially horizontally disposed pipe 10 provlded with a suitable valve 11, the stem 11 of which is shown passing through suitable glands or acking 12, 13, to the exterior of chamber3 or manipulation. Pipe 10 is provided with any desired number of openm s 16, shown located at the lower part of sa d pipe, and valve 11 is shown provided w th corresponding openings 11 to coact with the openings 10, whereby compressed air flowlng through pipe 8 to pi e 10, and thence through pipe 8, may a sorb and carry with it the desired proportion of hydrocarbon 4.

At 14: is indicated a plate at a desired distance below openings 10 of pi e 10, being shown secured to pipe 10, the p ate 14 being shown curved beneath pipe 10, whereby any air that may blow throu h openings 10' into chamber 3 is deflecte from the sides of plate 14. \Vithin pipe 8- a fan 8" may be placed to assist in mixing the heavily charged carbureted air flowing through said pipe. A pipe 15 connects with pipe 8 and leads into the lower portion of receiving chamber 16, and is shown having a branch or outlet 15 Within chamber 16 communicating with a casing or shell 17 in the lower part of chamber 16. Casing 17 is provided at its upper portion with outlets for causing fine division or comminution of the relatively heavily-charged air flowin from chamber 3 through pipe 15. For tfiis purpose I have shown a top 17 on casing 17 provided with relatively minute orifices or perforations 17, which top may be of foraminous material. Within the chamber 16 are any desired number of screens 18, spaced at suitable distances apart one above another, and shown inclined, through which carbureted air is caused to flow.

At 19 is a fan of any suitable or wellknown construction located within chamber 16 and above casing 17, the fan being caused to rotate by the flow of carbureted air from casing 17 to aid in comminuting and mixing the same. Piping 20 communicates with chamber 16 and with a tank 21 having an outlet pipe 22, which may be controlled by a suitable valve 23. At 24 is shown a pressure reducinfg or controlling valve, which may be 0 any wellknown construction, located in the hue. of pipe 20 to cause OF NEW YORK, N. Y., ASSIGNOR TO POLAR GAS COMPANY,

N. Y., A CORPORATION OF NEW YORK.

the delivery to tank 21 of carbureted air at any desired reduction below the pressure of the primary air in tank 1.

At 25 is a valve shown between pipes 8 and 15, which may be adapted to cut of? communication between chambers 3 and 16, and also may permit exhaust of gas through the outlet 25 when required. From tank 1 pipe 26, which may be controlled by a valve 27, leads to casing 17, and is shown provided with a jet opening or nozzle 26 communicating with casing 17 beneath and thus adjacent to the delivery end of pipe 15:. A valve 28 may be provided to permit draining of chamber 16, casing 17, and pipe 26 when required.

In the modification shown in Figs. 6 and 7, instead of providing the top of chamber 17 with the orifices or perforations 17, 0215- ing 17 may be provided with a desired number of outlets 17 shown having narrow slits or delivery nozzles 17 to cause heavily carbureted air flowing from casing 17 to be finely divided.

Air under desired pressure is maintained in tank 1, and chamber 3 is charged to the desired depth with hydrocarbon, such as kerosene oil, or other desired liquid, and valve 11 is set in the desired position, and then the compressed air is caused to flow through pipes 8,10,8 15 and 15, whereupon such air will, in its passage through pipe 10, carry with it a portion of the hydrocarbon or oil to produce what may be termed a heavily-earbureted air which will flow, under pressure, into casing 1.7. Air under pressure is also caused to flow through pipe 26 and its nozzle 26, and such air is delivered into casing 17 adjacent the delivery of the heavily-carbureted air into casing 17, and is blown into the stream of heavilycarbureted air, causing such heavily-carbureted air to be diluted and a mixture made of the desired carburetion, which carbureted-air will be caused to flow under pressure from casing 17 through the orifices or outlets thereof, and into chamber 16, and in its passage through the screens 18 will be caused to become more intimately mixed, the fan 19 aiding in producing such mixture. The thus-produced desired carbureted air will then be delivered into tank 21, under such pressure as desired by reason of the action of the reducing valve 24, and from tank 21 the carburetedair will be drawn for illuminating or power purposes, or for other desired uses.

By means of my invention it will be seen that the production of the desired carbureted air is continuous and without requiring heating the hydrocarbon.

A particular advantage of my invention is that kerosene oil may be minutely coinbined with the desired proportions of air in the production of a carbureted air or gas,

without requiring the kerosene oil to be heated, thereby retaining in the kerosene oil all of its natural qualities to the point of consumption, as distinguished from the loss that may be otherwise occasioned where kerosene is heated to volatilize it, as for carburetion purposes, before it is consumed in the form of carbureted-air.

Changes may be made in the details of construction and arrangements set forth within the scope of the appended claims, without departing from the spirit of the invention, as for instance, instead of using tank 1, the pipes 7 and 26 may be connected direct with one or more sources of compressed air, having any desired pressure.
